Perhaps you should try some spelling variations:
"informationen visuelle" » "informationen aktuelle", "informationen erstellen", "information visually"
"informationen liefern" » "informationen leben", "informationen lernen", "informationen entfernen"
"informationen intern" » "informationen internet", "informationen unter", "informationen index"

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (((((("informationen intern") OR ("informationen liefern"))) OR ("annotationen aktuelle"))) OR ("informationen visuelle")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"informationen intern\") OR (\"informationen liefern\"))) or (\"annotationen aktuelle\"))) or (\"informationen visuelle\"))".
• Removing quotes may allow a broader search: (((((( informationen intern ) OR ( informationen liefern ))) or ( annotationen aktuelle ))) or ( informationen visuelle )).
• Adding a wildcard symbol may retrieve word variants: (((((("informationen intern") OR ("informationen liefern"))) or ("annotationen aktuelle"))) or ("informationen visuelle"))*.
